Enterprise Innovation Capability:
The company places high importance on technological innovation and intellectual property protection, having acquired intellectual property rights for core technologies through independent research and development. The company currently holds 14 valid utility model patents, which provide core technical support for its main products, enabling their technical performance to lead domestically and enhancing the company's competitiveness. Examples are as follows:
(1) A Mechanical Seal Device for Boiler Feedwater Pumps (ZL202323376322.X). By adopting this patented technology, the operating temperature of the dynamic ring, stationary ring, and spring can be effectively reduced, allowing the core sealing components to operate under low-pressure conditions, extending component lifespan, and improving the performance of the seal.
(2) A Mechanical Seal Device for Sewage Pumps (ZL202323376321.5). The application of this patented technology can effectively intercept large-particle impurities in the medium, reduce direct wear on the dynamic and stationary rings caused by hard particles, enhance sealing effectiveness, and prolong the service life of the seal.
(3) A Mechanical Seal Device for High-Pressure Oil Pumps (ZL202323462471.8). Utilizing this patented technology helps effectively reduce the fluid pressure on the sealing end face, prevent sealing failure caused by the rupture of the high-temperature oil film, maintain a stable liquid film lubrication state, and improve the performance of the seal.
(4) A Mechanical Seal Device for Double-Suction Pumps (ZL202323462470.3). This patented technology avoids direct contact between impurities and the elastic components, improves the performance of the seal, and extends the service life of the equipment.
Technology transfer results:
Our company is a high-tech enterprise with complete independent intellectual property rights, specializing in the technical R&D, product design, production, and sales of mechanical seals and general mechanical seals.
